Hamilton and published by . This book was released on 1969 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of marine sediments in three major environments of the North Pacific: the continental terrace (shelf and slope), abyssal plain (turbidite), and abyssal hill (pelagic). Laboratory values of the mass physical properties of the sediments (e.g., sound velocity, density, porosity, grain size, and others) are measured and computed and their empirical relationships and environmental differences are discussed.

Book excerpt: A study of the acoustic and related properties of the sea floor in three major environments of the North Pacific: the continental terrace (shelf and slope), abyssal plain (turbidite), and abyssal hill (pelagic). Discussions cover the correction of laboratory to insitu values, and the prediction of in situ values. The methods developed are applicable to other areas and sediments.

This book was released on 1969 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of the elastic properties of marine sediments from three major environments of the North Pacific: the continental terrace (shelf and slope), abyssal plain (turbidite), and abyssal hill (pelagic). Elastic constants are measured and computed. Discussions cover elastic and viscoelastic models, compressibility, bulk modulus, rigidity (shear) modulus, Lame's constant, Poisson's ratio, density, shear- and compressional-wave velocities, and interrelationships between these and other physical properties.

Available in PDF, EPUB and Kindle. Book excerpt: The general objectives of this investigation were to determine and study those characteristics of the sea floor that affect sound propagation and the prediction of sonar performance; to support underwater acoustics' experiments and theory by furnishing information on the mass physical properties of sediments and rocks in the form of geoacoustic models of the sea floor; and to develop models of the sea floor which include gradients of sound velocity and attenuation, density, and elastic properties. Specifically, the minor objectives were to revise and review earlier work on the relations between frequency and attenuation of compressional (sound) waves in marine sediments and on the relations between attenuation and sediment porosity. The major objectives were to determine and predict variations of the attenuation of sound waves with depth in the sea floor.

This book was released on 1969 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: In situ measurements were made of the velocity and attenuation of compressional waves and of velocities of Stoneley waves (from which shear-wave velocities were computed) at six stations in the sea floor off San Diego, California. Water depths ranged from 20 to 1130 meters, and sediment types ranged from medium sand to clayey silt. Sediment densities, porosities, and grain sizes were measured in samples taken at each station. The unique data obtained allowed tentative evaluations of models and equations, and computation of constants, for elastic and viscoelastic saturated, porous media. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Acoustic relaxation theory for visco-elastic media provides for sound propagation in unconsolidated marine sediments. For the frequency range of 14 to 200 kHz, dispersion for compressional-wave and shear-wave velocity is negligible for all practical purposes, but sound absorption shows significant changes. (Author).
Download or read book Physics of Sound in Marine Sediments written by Lloyd Hampton and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomenon of sound transmissions through marine sediments is of extreme interest to both the United States civilian and Navy research communities. Both communities have conducted research within the field of this phenomenon approaching it from different perspectives. The academic research community has approached it as a technique for studying sedimentary and crustal structures of the ocean basins. The Navy research community has approached it as an additional variable in the predictability of sound trans mission through oceanic waters. In order to join these diverse talents, with the principal aim of bringing into sharp focus the state-of-the-science in the problems relating to the behavior of sound in marine sediments, the Office of Naval Research organized and sponsored an invited symposium on this subject. The papers published in this volume are the results of this symposium and mark the frontiers in the state-of-the-art. The symposia series were based on five research areas identified by ONR as being particularly suitable for critical review and for the appraisal of future research trends. These areas include: 1. Physics of Sound in Marine Sediments, 2. Physical and Engineering Properties of Deep-Sea Sediments, 3. The Role of Bottom Currents in Sea Floor Geological Processes, 4. Nephelometry and the Optical Properties of the Ocean I'laters, S. Natural Gases in Marine Sediments and Their Mode of Distribution. These five areas also form some of the research priorities of the ONR program in Marine Geology and Geophysics.

Available in PDF, EPUB and Kindle. Book excerpt: The developments in the field of ocean acoustics over recent years make this book an important reference for specialists in acoustics, oceanography, marine biology, and related fields. Fundamentals of Acoustical Oceanography also encourages a new generation of scientists, engineers, and entrepreneurs to apply the modern methods of acoustical physics to probe the unknown sea. The book is an authoritative, modern text with examples and exercises. It contains techniques to solve the direct problems, solutions of inverse problems, and an extensive bibliography from the earliest use of sound in the sea to present references.Written by internationally recognized scientists, the book provides background to measure ocean parameters and processes, find life and objects in the sea, communicate underwater, and survey the boundaries of the sea. Fundamentals of Acoustical Oceanography explains principles of underwater sound propagation, and describes how both actively probing sonars and passively listening hydrophones can reveal what the eye cannot see over vast ranges of the turbid ocean. This book demonstrates how to use acoustical remote sensing, variations in sound transmission, in situ acoustical measurements, and computer and laboratory models to identify the physical and biological parameters and processes in the sea. * Offers an integrated, modern approach to passive and active underwater acoustics* Contains many examples of laboratory scale models of ocean-acoustic environments, as well as descriptions of experiments at sea* Covers remote sensing of marine life and the seafloor* Includes signal processing of ocean sounds, physical and biological noises at sea, and inversions* resents sound sources, receivers, and calibration* Explains high intensities; explosive waves, parametric sources, cavitation, shock waves, and streaming* Covers microbubbles from breaking waves, rainfall, dispersion, and attenuation* Describes sound propagation along ray paths and caustics* Presents sound transmissions and normal mode methods in ocean waveguides
